UI droppable for a project, I would like to detect the opposite to the accepted event.
I mean that if i drag and drop a not accepted container do some action, so far I haven't found any way to detect it.

$( function() {
//The red div becomes draggable
$(".red").draggable({
revert : function(droppableContainer) {
if(droppableContainer) {
//If it's droppable :
alert('valid');
$(this).css("visibility", 'hidden');
}else {
//if it's not droppable :
alert('invalid');
}
return(!droppableContainer) //returns the draggable to its original position
}
});
//The pink div becomes draggable
$(".pink").draggable({
revert : function(droppableContainer) {

$(".dropdiv").droppable({accept: '.pink',});

<p>Drag</p>

<div class="dropdiv ui-widget-header" style="width: 400px; height: 150px; padding: 0.5em; float: left; border:3px solid black;">
<p>Drop here</p>

Found out that using the
revertoption for the draggable event can solve it.
